1st measurement:

mpyc                              = 30.7628 g

mpyc + test item                  = 35.97597 g

mpyc + test item + n-heptane = 67.6015 g

mCD394                        = 5.214 g

mheptane                      = 31.625 g

Vheptane                      = 46.2363 mL

Vtest item = 49.7064 mL- 46.2363 mL = 3.4701 mL

ρtest item                          = 5.214 g / 3.4701 mL = 1.502 g/mL

 

2nd measurement:

mpyc                               = 30.7629 g

mpyc + test item                  = 35.5985 g

mpyc + test item + n-heptane = 67.4023 g

mCD 394                        = 4.8356 g

mheptane                       = 31.8038 g

Vheptane                       = 46.4968 mL

Vtest item                         = 49.7064 mL- 46.4968 mL = 3.2096 mL

ρtest item                         = 4.8356 g / 3.2096 mL = 1.507 g/mL

relative density - calculation:

To calculate the relative density D420at 20 °C, the measured density of the test itemρTIat 20 °C is divided by the density of waterρW4at 4 °C (0.9999750 g/cm³). The relative density at 20 °C D420is calculated according to the following equation: D420 =ρTI /ρW4

D420:   Relative density (without dimension) of the test item measured at a temperature of 20 °C compared to the density of water at 4 °C

ρTI:      Density of the test item measured at a temperature of 20 °C ± 0.01 °C in g/cm³

ρW4:    Density of water at 4 °C in g/cm³

D420 = 1.5045 g/cm³ / 0.9999750 g/cm³ = 1 .5045

Conclusions:
The relative density of the test substance is 1.5.
